Beit known that l, Jon-N C. HULL, a citi-. zen of the United States, residing at Gosport,

in the county of Niagara and State of l\ew York, have invented a new and useful Spraying-Nozzle, of which the following is a s pech cation. l

In spraying nozzles of theftype disclosed in' Patent, No. 848,995, granted to A. B. Hull on pril 12, 1907 and in the. patent of JohnU. ull, dated July 2, 1907, experience has deinonstrated that with certain classes offheavy insecticides, the whirling body of liquidin the chamber prior to'its escape will grind an oening downwardly through said-body into t e channel, thus quickly destroying the nsefulness of the nozzle.

Theprimary object of the j resent invention isto4 provide'means Whic will prevent this grindlngaotion, vand at the saine time Willgreatly improve the structure by producing' amuch finer spray under less pressure.

Twoembodiments of the invention'arc disclosed in the accompanying drawings, where- A tortuous channel 9 is formed in the body and ovens through the flat iront face :it one side o lits center, the discharge portion of seid channel being disposed obliquely to said front face. A cap, oornnrising e.. flanged ring 10, is threaded u on t e periph ry oi' the body, and has ino osed therein, a disk il oi' steel or other hard mater This disk has a central orice l2. pacinng washer i3 is interposed between `the .margin oi' the disk f and the margin of the irontace 8, seidA Washer being located outside the ldischarge mouth of the channel 9. This 'Washer thus serves to space the disk` from the flat front face 8, and rovides an inclosed chamber, With which t e tortuous channel 9 and-discharge orifice 12 communicate. A. plug is employed that has a central boss 14 located on the iiat iront face S in line with the orifice. 12, but spaced 'from the disk 11. This bess 14 is preferably ol' steel or vhard instal, may be secured in place in a variety ci w: Thus in the embodiment disclosed in Fi s. f3 v3 and 4, it has a shank 15, which ps throughM a centrsl opening formed in the iront Wall 8, said shank being upset to mainN es 'ta-in the boss in position. A socket 1G, may however, beffornied in the iront face and the boss 17 seated the-rein Moreover ssid boss may be of different shapes, for instant' may have a flat outerface, as shown in i 2, or it may be in the form of a cone, i trate-d in Fig. 5. lt will thus be evident the whirling body ol insecticide in 'ti closed chamber caused by the 'forward obliquely disposed stream delivcred l;t channel, is reduced it its vortex between hard walls, which it'cennot materially Thus the` defects noted in the prelim ortion of the speci'lication elimine. but experience has also demonstrate with this particular' arrangement, a iiner and more widely diiiused spray is prf duced with a less pressure than with the i dinnrry Well known type to which re has already been inode. The boss t performs a double function in the por ieu relation described, andin the it iris" exposed so tl the plug een bei' Q S tages f he ein described be appei'ent'to those skilled. out further d1,- ciiption, and stood that viii :ius changes in proportion. and minor flete tion, may be or'ted to Wl i ironi the spin( or sacrificing 'L vantsges of 'the invention.

Having illy described n what i ol. new, and desi Letters Patent, is:--` l lmet spraying nozzle comprising; f l having e Fluid coidusting4 channel through the discharge portion of Wiii Y thi l l "ront end of the body omis e and at one sido oi a cap seemed to tliebody and het f' inlexih'le front nell that covers thi in an'inclosed chamber in which the liquid vde ivered by the channel is given ak rotary winch opens through the rear sideof the body, the discharge end opening through the front end of the body at one side of the center, a boss located centrallyonn the front side and having astem extending through the body into the inlet end of the channel,v and a cap located over the front side of the body in spaced relation to the boss and having a central openingin line therewith:

3. Aspraying nozzle comprising a single iece body having a'substantially flat fronty iace and a substantially central rearwardly projecting boss that is threaded to receive a conduit, said body having a channel eX tending through the boss and havincr its discharge portionopening through the iiat front face. of the body at one side of its center and obliquely to said face, a hooded ca threadedA on thi#J front end 'of the body an having a detachable front wall or disk provided with a', discharge orifice, a packing washer located in the cap and inter osed between said front Wall or disk and t ie front face of `the body,

the washer surrounding the discharge end of the channel and the dischargeA orifice and forming a chamber between the front wall ojr disk and the front face ofthe body, and a tapered head or boss of harder material than the body secured to and projecting beyond the front face of' said body, said boss termi.-

nating short of the front wall or disk, thereby contracting the central portion of the chamber at the discharge orifice and constituting means for preventing the wear of the'bddy in rear of said orifice.

4'. A spraying nozzle com rising a lbody having a channel, the inlet en of which dpens' through therear side of the body, the discharge end opening through the front face of the ody at one side of its center andA disposed obliquely to said face, a cap located 4over the front face of the body in spaced relation to the front face and having a central opening in line therewith, said body also having a central opening in line with the cra-lp opening and communicating with the i et end of the channel, and a plug having a shank passingthrough and closing said centra]v opening and having the. front lend eX- posed at the front face ofthe body. ,A

-5. A spraying nozzle comprising a body having a fluid conducting channel there-V through, the discharge portion of which opens through the front end of the body and ob? liquely to its front face and at one sido ofv its center, a cap secured to the bodyover said ,front face and having an inexible rontwall s aced from the face, termin l an inclosed chamber in which the liquid de ivercd by the channel is'given a rotary' movement'dueto the obli ue disposition of said channel, said front wal having a central discharge orice in line ,with the center of the body, `ind a boss of harder material than the body secured thereto and projecting centrally from and beyond the frontface of the bod terminatfing short of the front wall an posed in rear of the front oriice, ai boss tapering toward the orifice and con\tracting the central portion of the chamberat the same time constituting means for'preventing the wear of the center of the body by the rotating fluid. i l

In testimony, that I claim the foregoing as my, own, I have hereto aHiXed my signature in the presence fof two witnesses. 'Y
